Fig. 3 is a plan section of the-same on the hne-33 of Fig. 2; end 1 i vFig. 4: 15;], section taken on the line 4+4 of Fig 2.

Referring to the drawing, reference eharto actor l1 indicates a portionofe needle bed provided with upwardly extenc'linp; needle guidesorpnrtitions 12 between which the knitting needlesvsre moved by thejacks (not shown). Each knitting needle consists of e knitting hookmember 13 and a holding hook member 14.,the knitting hook mernberedandengaging the new yarn or thread and returning with it through a.previously knitted loop forming a, new knitting loop, the old loopbeing, held up by the holding, hook and then dropped over the which isbrought in by the knitting The knitting hook member consists of e sheetof meta] folded back upon itself it upwardly extending spaced wings 16at the front-end a hook 17 formed nt the forward end of the junctioniii-betweentheside portions of theimemhen, said hook being thereafterbent up and over as indicated in Figs. 1 and 2. Theknitting hook memberis bent down'in the inclined position shown in the/figures so that thetop end of the knitting hook is dis posed snlstantinlly iniine with theinnerv face of the bond 15. The bed of the knitting hook member extendsrearwardly from the wings 1G and up into' a portion 18 adapted forengagement vportion 19 of 1t extends upnndforwardly forminga guide forthe tail of the holding hook member. Rearwerdly from a point 21',

a reinforcing plece is positoncd between the upwardly extending parts ofthe knitting hook men'iber so that back of the point 21 thek'nittinghook member consists of three lan iinntions solidly connected togetherin any snitilble fashion.

Two horizontal slots 23 fire provided in slots are narrow ledges or lips24; and 25, said slots acting as guldes' for the holding hook'in itsmdvement. 7 e v 'Ilheholdingr hook member 15} is provided 105, initslorwerd end with at holdinn hook 26 by the jack. 'A 90 e the win 5 16and above and beneath said i movable in the slots 23 and has a tail 29extending in between the shank of the knitting hook member and beneaththe forwardly extending part 19, curved'lips 31 bein provided to engagethe shank and part 19 0% the knitting hook member to maintain thedesired relative relation between the parts. The end of the tail is'bentback to provide a spring tongue 32 which pressing against one needleguide and forcing the tail :29 against the other spring-holds theholding hook against movement.

At the beginning of a knitting operation the parts are arranged as shownin Fig. 2, from which position the knitting hook member is advanced topick up the yarn to form a new loop. The old loop, which is resting inthe knitting hook when the parts are arranged as in Fig. 2, slides backup along the downwardly extending stem of the needle until it rests inthe holding hook (as indicated at a in Fig. 1). During this forwardmovement of the knitting hook the holding hook remains stationary byreason of engagement of its tail with the needle guides and it staysstationary until the studs 28 engage the rear ends of the slots 23whenit advances the slight remaining distance of the stroke of the knittingneedle. Upon the return of the knitting needle under the action of thejack, the knitting hook member moves back first unaccompanied by anymovement of the holding hook member, this member remaining stationaryuntil the parts have assumed the relative position shown in Fig. 2 withthe old loop held up by the holding hook until the holding hook extendsabove the knitting hook and the old loop is cast 0E over the new. Themovement of the needle in each direction need only be slightly more thanthe length of the slot.

The needle guides 12 are arranged so that the studs in action are alwaysin front of them and the space between the guides need therefore only bethat which will accommodate the shank of the knitting hook member. Theneedle therefore extends out beyond the guide an appreciable distanceand I provide a needle bed extension 33 on which the needles slide, thisbed being cut away at the front at 84 to permit the downwardly in clinedfrontend of the needle to be retracted the desired distance andhavingupwardly extending low guides 35 above which the studs 28 may ass.

The ends of the studs extend over in front of the partitions or guidesand in constructing the needle b' d it is only necessary there fore tospace the guides far enough apart to permit these studs to have thedesired freedom of movement with respect to each other.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing description, and it will beapparent that various changes may be made in the form, construction andarrangement of the parts without departing from the spirit and scope ofthe invention or sacrificing all of its material advantages, the formherembefore described being merelya preferred embodiment thereof.

2. A needle for knitting machines, comprising a knitting hook member anda holding hook member having conjoint and relative movement in knitting,the holding hook member being disposed in the plane above and parallelto the knittin hook member, said hooks having a pin an slot connectionfor guiding them in their relative movement in both directions.

3. A needle for knitting machines, comprising a knitting hook memberhaving a substantially straight body and a downwardlv extending knittinghook at its end, and a holding hook member-carried thereby andhaving'relative movement in a. straight line parallel to said body andabove said knitting hook member. t. A needle for knitting machines,coffiprising a knitting hook member formed of a metal sheet bent toU-formation, and a holding hook member embraced thereby, the forward endof said sheet being formed into a. knitting hook and bent down tobeneath the lower edge of said holding hook member.

5. A needle for knitting machines, comprising a holding hook member anda knitting hook member, the latter formed of sheet metal and bent toprovide a guide for the forward end of said holding hook member,

the front end of said knitting book being member being disposed in 'aplane aboveand" parallel to the knitting hook member, said hook membershaving cooperating parts for guiding them intheir relative movement inboth directions, and means independent of the yarn operated upon forproducing relative movement between said members in knitting.

7. A needle for knitting machines, comprising a knitting hook memberhaving a.

substantially straight body and a downwardly extending knitting hook atits end and a holding hook member carried thereby 55nd having relativemovement in a straight line parallel said body and above said knittinghook member, and means independent of the yarn being operated upon forproduo ing relative movement of said members.
